end a suitable valve 23tby means of which the opening 24 is controlled. It will be observed that the coil 20 communicates with ithat has a small opening 26 that a pin 27 passes through when the valve is closed.

Those skilled in this artvunderstand the function of the pin is to keep clean the opening 26 when the valvev is closed so that when it is opened the opening will be iree for the passage of vapor through it.l

A' suitable receptacle 28 is sustained below the coil 20 andthe receptacle contains a suitable amount of mineral wool' 2 9 for the purpose ot being saturated and lighted.

In operation the valve 23 is closed vand the mineral wool 29 saturated with alcohol,v gasoline or the like, and then lighted by a match. The flame liowing upward from this mineral wool, strikes the coil 20 and incidentally warms it and the outlet end of the valved' passageway. This coil being heated by the flame from the mineral wool, the oil therein is converted into a' vapor. opening the valve 23 the vapor from vthe coil flows into the heated end oi' the valved passageway and through the nipple 25 into the mixing chamber Ll., From this mixing chamber the mixed vapor and air flow through the 4opening' 7 and strikes against the imperfor-ate part 6, and then flows into the burner. The burner then being lighted, theA retort tube 2 becomes heated and vapor is generated in the tube and flows intothe coil and through the valved passageway to the mixing chamber in the manner just explained. In initially starting the burner the valvei23 is closed and themineral'wool 29 is saturated with a Volatiley liquid and lighted. rlhe llame and heat from the wool heats the outlet end of the passageway 21 and heatsthe coil 20. Attention is called to the fact. that this coil 20 ismuch smaller' than the tube` 2 and is made of such material that the coil becomes quickly heated. l Said heat and flame are concentrated around the coil by means oit' an upwardly inclined hood 30, the said hood beginning substantially at the passageway 2l and extendsupward, its upper end 3l resting on the front end ot the retort tube 2. The hood vertically surroundsy said coil and has its inner end '32 clamped to a bracket'BS that extends down- Then by The rear and inlet end of the retort tube 2 is supported upon a. suitable bracket 38,

the lower end of the bracket turned laterally coilpisvaporized so that when the valve 23 is opened, vapor at once flows into the mixing tube 4l, thence to the chamber 5 at its rear end and through the opening 7 into the burner G. The flame from the Iburner at once heats the retort tube so thatthe liuid in the retortis vaporized, which causes at once ample vapor for the operation oi the burner and ample-for the auxiliary burners;

The six'pointed star shaped burners we findv to be exceedingly efficient, and gives abetter result than the ordinary substantially round-shaped burners;

We call attention also to the shape of the chamber 5 at the rear end of the mixing tube.

yThis chamber iorms in eiiect a pocket'to receive -any condensatioir oi the vapor in the starting of the burner. When the burner is started, the mixing tube and passageway and the tubes 9 and `l() that connect with `the auxiliary burners 16, are relatively cold,

so that a very small portion o the vapor entering these parts will be in the lirst instance condensed, and by means of shaping the chamber 5 to form a pocket, this condensed hydrocarbon will be contained in the chamber which prevents it from reaching the burners.` IVhen the burner becomes heated, then this condensed hydrocarbon becomes 'heated and is vaporized so' that'it will not continue to accumulate in the said chamber;

By reference to Figure 2 it will be seen thatthe auxiliary burners l5 and 16 have the same shape as the burner l I'so that theyk operate exactly 'as the burner ll operates.

It is found in operation lthatv the burner hereindisclosed isvery quickly started and When inv 'operation provides vample vapor for the main burner and for 'the'auxiliary burners. Located betw'een'the main burner and the auxiliary burners in any desired position are handles 4 0; These handles are for operating valves (not shown) that control the flow of vapor tothe respective auxiliary burners. By means of these handles one or both of the auxiliary burners may be 'cut off, or supplied with vapor.

We have'explained in considerable detail' the preferred construction used in carrying out our'improvement, but we desire it understood that`variationsmay be made so long as those variations will Vcomewithin a fair interpretation of the appended claims.

Having thus' described ourinvention,

v l. A hydrocarbon burner comprising-a spectively with the passagewa what we desire to claimand secureiby Let,- ters Patent is:

burner housing, a mixing `chamber located below the housingandextending throughout its length, its rear .end in communication with theburner housing, a retort tube extending over the said burner from its' rear to its front end, a valve controlled `end of the mixing chamber being enlarged to form a depending pocket for the condensed vapor substantially as described. q

2. yA khydrocarbon burner comprising a l y lburner housing, a mixing chamber below burner housing, a mixing tube located below the housing and extending throughout its width, a retort extending across the top of the burner, a valved passageway .communicating with the front end of the mixing chamber, the retort-and passageway being in a vertical line above each other, a vertical coil having its ends connected respectively with the passageway and with the front end of the retort tube, the burner housing having at its rear end ya rearwardly projecting imperforate portion andthe mixing chamber having communication with cthe housing immediatelybelow the imperforate portion whereby the vapor is distributed within the kburner and a lighter located vertically `below the-valved passageway and the said co il,`the parts operating for the pur pose specified.

3. A hydrocarbon burner comprising a burner housing, a mixing chamber belowvthe burner housing, a retort tube extending sageway connecting `with thesaid mixing adjacent end of the retort, a vertically arrangedycoil comprisinga horizontal spiral across the `topfof said burner, a vapor pas-` chamber and located vertically below the located immediately between thesaid passageway. and the said retort and forming communication between said retort and said passageway, a valve controlling the passage of-,vapor from said passageway, van initial lighter located below and in a line with said passageway, and the said coil, said horizontal spiral being wider than the said vapor passageway whereby 'the' said initial lighter quicklyheats the passageway andthe exposed portion of the Vcoil and jquic'kly "supplies vapor to be fed to themixingtcham c bers and thence to said burner. g

4. A hydrocarbonV burner comprising a the burner housing, a retort tube extending across the top of said burner, a vapor pasn sageway connecting with' the saidrmixmgy chamber and locatedvertically below the adjacent end `ofthe retort, a vertically a1'- ranged coil comprising a horizontal spiral located immediately between the said pars- -sageway and the said retort and forming communication between said retort and said lighter located below and ina line with said e 1o passageway, a valve controlling the passage V passageway and the said coil, said horizony i tal spiral being wider than the said, vapor passageway, said coil made of a' pipe smaller 1n diameter` than the retort tube and 'the vapor passageway.
